Overview

The Grundfos fieldbus concept is the ideal solution for complete control of pumps and pump systems. The Communication Interface Module (CIM) and the Communication Interface Unit (CIU) enable data communication via open and interoperable networks.

The Grundfos CIM/CIU communication interfaces offer ease of installation and commissioning, user-friendliness, and great value for money in the long term. All modules are based on standard functional profiles for easy integration into the network and easy understanding of data points.

CIM modules are add-on modules that allow communication with 11 to 22 kW E-pumps and the new Dedicated Controls for wastewater pumps.

The CIU communication interface unit is for products with a GENIbus interface such as small E-pumps, circulation pumps and boosters. CIU units have an integrated 24 to 240 V power supply and are prepared for wall-mounting or DIN-rail mounting.

The CIM/CIU interfaces support the following fieldbus standards:

LON

PROFIBUS DP

Modbus RTU

SMS/GSM/GPRS

BACnet MS/TP

PROFINET IO

Modbus TCP

BACnet IP

Applications

CIM/CIU 100/110 LON is mainly used for HVAC applications

CIM/CIU 150 Profibus DP is mainly used for factory and process automation

Communication interface for BACnet MS/TP (Data Sheet)

The CIM/CIU 300 is a standard interface for data transmission between a BACnet MS/TP
network and a Grundfos pump. It makes data exchange possible between pumps and a
SCADA system or supervisory controller.

Communication interface for LON (Data Sheet)

The CIM/CIU 100 and CIU 110 is a standard interface for data transmission between a LON network and a Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems and a building management system.

Communication interface for Profibus (Data Sheet)

The CIM/CIU 150 is a standard interface for data transmission between a Profibus DP network and a Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems and a PLC or SCADA system.

Communication interface for PROFINET IO (Data Sheet)

The CIM/CIU 500 is a standard interface for data transmission between a PROFINET IO network and a Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems and a PLC or SCADA system.

Communication interface for Modbus (Data Sheet)

The CIM/CIU 200 is a standard interface for data transmission between a Modbus RTU network and a Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems and a PLC or SCADA system.

Communication interface for Modbus TCP (Data Sheet)

The CIM/CIU 500 is a standard interface for data transmission between a Modbus TCP network and a Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems and a PLC or SCADA system. Via a rotary switch you can also change the protocol to e.g. PROFINET IO.

Communication interfaces for GSM/GPRS -wastewater (Data Sheet)

SMART Digital - DDA with Profibus (Data Sheet)

The SMART Digital dosing pump range DDA is available with an E-box which hold a CIM 150 Profibus -DP interface. This is a standard interface for data transmission between a Profibus DP network and a Grundfos pump. It makes data exchange possible between Grundfos DDA and a PLC or SCADA system.
